We have had some problems with getting the latest version of sddm to work
properly so I have been investigating lightdm.
I had a bit of trouble getting lightdm to work, but finally figured it out.
I am using:
lightdm-1.24.0:
./configure \
--prefix=/usr \
--libexecdir=/usr/lib/lightdm \
--localstatedir=/var \
--sbindir=/usr/bin \
--sysconfdir=/etc \
--disable-static \
--disable-tests \
--with-greeter-user=lightdm \
--with-greeter-session=lightdm-gtk-greeter &&
make &&
sudo make install &&
sudo cp tests/src/lightdm-session /usr/bin
lightdm-gtk-greeter-2.0.3:
export CFLAGS="$CFLAGS -Wno-declaration-after-statement" &&
./configure \
--prefix=/usr \
--libexecdir=/usr/lib/lightdm \
--sbindir=/usr/bin \
--sysconfdir=/etc \
--with-libxklavier \
--enable-kill-on-sigterm \
--disable-libido \
--disable-libindicator \
--disable-static &&
make &&
sudo make install
Both build and install without complaint. I had quite a problem figuring
out the need for cp tests/src/lightdm-session /usr/bin, but with that the
system seems fine.
The configuration is a bit complex. I basically used the files at Arch:
https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/lightdm
I modified xsession with s:$HOME/.profile:$HOME/.bash_profile: and
installed it in /etc/lightdm/
I created /etc/pam.d files lightdm, lightdm-greeter, and lightdm-autologin
with:
auth include system-auth
password include system-password
account include system-account
session include system-session
where the system-* are the files created in the BLFS pam page.
We may want something else, but I do not know what right now.
I created the following directories:
/var/lib/lightdm 4770 lightdm lightdm
/var/cache/lightdm 0711 root root
/var/lib/lightdm-data 0755 lightdm lightdm
/var/log/lightdm 0711 lightdm lightdm
the 4770 and0711 permissions seem quite weird to me. I do not see a
need to use something other than 0770 for any of the above.
I added the lightdm.rules file from arch in /usr/share/polkit-1/rules.d/
I then just ran the lightdm program as root from the command line. The
greeter came up and mouse/keyboard were fine.
Customization is another topic. For the most part, google discusses
apt-get or yum which do not apply to us, but it appears to be mostly
setting up /etc/lightdm/lightdm-gtk-greeter.conf. Also, there is a python
based gui to do customization, lightdm-gtk-greeter-settings.
I can try a boot script similar to the sddm version, but have not done
that yet.
------
The question is whether we should drop sddm and add lightdm. We still
have lxdm and, in the systemd version of the book, gdm.
